I have the following string:

tagged.big) AND tagged.medium

I need to extract everything from this string that starts from tagged. and ends with one or more whitespaces or )

This is my current regex pattern:

tagged.[),S]+

From the example string I expect:

tagged.big
tagged.medium

but right now it returns:

tagged.big)
tagged.medium

What am I doing wrong and how to fix it?

In your regex you use tagged.[),S]+ which contains a character class with ), comma and S which matches not a whitespace character. The S also matches a comma and ) so that could be shortened to just S+. But that would match too much.

To match your values, you could for exampe use a word character w or add to the character class what you would allow to match:

tagged.w+

Regex demo

That will match

• 
  tagged. Match tagged.


• 
  w+ Match 1+ word characters

Regex demo

Final pattern : tagged.[^Ws]+ (You can see a further explanation on the site)

So it follows:

• 'tagged.' : matches any string with start with tagged.
  


• [^ ]: this matches a single character which is NOT presented on the set.


• [^Ws] : matches a single character which is not a non-word or whitespace


• 
  + : quantifier greedy, matches one or unlimited times the set.
